If you are planning on adding to your house, then you want your room addition plans to be both conceptual and practical. I tend to favor room addition plans that do both so that you can accomplish both the concept and the practicality at the same time. In any case, think abo0ut what you want out of the new space. Do you want a new bathroom, or do you want to add a spare bedroom to the home? In some cases you may want to extend the home to allow for an entertainment and media space. Whichever direction you choose, be careful and detailed in the planning phase.
